Social inequality and incidence of and survival from cancers of the oesophagus, stomach and pancreas in a population-based study in Denmark, 1994–2003

Gastric cancer survival and affiliation to health insurance in a middle-income setting

“…Observed 1 and 5-year overall survival estimates for Bucaramanga in the special and contributive regimes were similar to relative survival estimates from Denmark, Scotland, Poland and Bulgaria, the lowest estimates within Europe [3,21], but survival for patients affiliated to the subsidized regime or those nonaffiliated to the health insurance system, and patients of low SS was much poorer, comparable to those of the indigenous Mapuches in Chile [20].…”

“…Internationally, most studies find gastric cancer to be more prevalent in the lower socioeconomic groups [1,3,16,17]. In Colombia, gastric cancer mortality was indeed found to be strongly related to educational level, with rate ratios of lowest versus highest educational levels of 2.6 and 1.98 for males and females, respectively [6].…”

“…Socio-economic inequalities in gastric cancer survival have been reported, although mainly from developed countries [1][2][3][4][5]. Possible explanations for these inequalities are differences in stage at diagnosis, subtype of gastric cancer, access to and use of effective treatments.…”

Esophageal Cancer Mortality during 2004-2009 in Yanting County, China

“…The decline trend of incidence and mortality might have something to do with changes in risk factors. Low socio-economic status was believed to be a risk factor for esophageal cancer (Wu et al, 2006;Baastrup et al, 2008). Yanting is a very poor area and its economic status has been below the average level of the whole Sichuan Province, in 1999 the average GDP per capita in Yanting was 3133 RMB, on the other hand the corresponding figures of Sichuan and China were 4473 and 6534 RMB, respectively (National Bureau of Statistics of China., 2000; Sichuan Bureau of Statistics., 2000).…”

Increased pancreas cancer in a bio­technological research laboratory

“…Its prognosis is poor [Baastrup et al, 2008], and the causal background remains largely unresolved except that smoking was recently established as an etiological factor explaining around 25% of the disease incidence [Secretan et al, 2009].…”
